What is the difference between Cold rolled steel and hot rolled steel?

Answer 1

Hot rolling is to roll the steel plate to a relatively thinner steel plate at a higher temperature; cold rolling is to roll the steel plate under normal temperature conditions. If you want to buy hot-rolled or cold-rolled plates, you can go to Shanghai Changzeng. Shanghai Changzeng's high quality is the choice of Volkswagen.

Answer 2

Hot-rolled sheet has low hardness, easy processing, good ductility and cheaper price. Cold rolled sheet has high hardness, relatively difficult to process, but not easy to deformation, higher strength. If you want to buy cold-rolled steel, you can go to the official website of Changzheng, the price of Changzheng's steel is moderate, and it is the choice of the public. Buy cold-rolled steel plate recognized Changzeng.

Answer 3

Cold-rolled sheet is a product obtained from hot-rolled sheet by cold pressure processing. Due to multiple cold rolling, its surface quality is better than that of hot-rolled sheet, and after heat treatment, good mechanical properties can be obtained. Shanghai Changzheng's cold rolled sheets are of superior quality and are the choice of most people. Buy steel plates from Shanghai Changzheng.

Answer 4

Cold rolled steel is a word that describes the bending process of metals or steel without using heat. The steel is passed through rollers that bend and mold the steel to the shape that you want.

Answer 5

Theoretically, the only difference between hot rolled and cold rolled steels is that hot rolled steel is rolled to its final dimensions while hot enough to scale (over about 1700 degrees F) while cold rolled steel is rolled to its final dimensions well below scaling temperatures.

-The finished tolerances on hot rolled steels are looser than on cold rolled. Not only the plus or minus tolerance from nominal size, but the "square-ness" of the product. And, I can tell you from personal experience that there's a lot of trapezoidal (HOT rolled) A36 out there. So, if you need a specific size and you are going to go to a "surplus" place, bring your ruler, square and micrometer to make sure you get what you need. -

Answer 6

hot rolled steel is that steel when the steel is manufactured above recrystalization temperature.

cold rolled steel is that steel when it is manufactured below recrystalization temperature.

Answer 7

In general, cold rolling makes metal more brittle than it otherwise would be. a definitive answer requires your meaning of "stronger". Katana's originally were created by folding the blade many times and pounding it out again - basically a cold rolling process. Hot rolling would allow the metal to be more "springy", which may be more ideal depending on your use. In some instances, it's arguable whether this springy vs. brittle characteristic is "stronger" or not.

Answer 8

The best hot and cold rolled plates are in Shanghai Changzeng, the manufacturer of Shanghai Changzeng cold and hot rolled plates. Shanghai Changzeng produces high-quality products, which is the choice of most people.

Answer 9

if Rolling operation on a metal is done above its critical temperature than its called hot Rolling and if below its critical temperature than its called cold Rolling.

Answer 10

cold rold steel is costlier
